Suppose that a shot putter can put a shot at the worldclass speed v0 = 15.00 m/s and at a height of 2.160 m. what horizontal distance would the shot travel if the launch angle θ0 is (a) 45.00° and (b) 42.00°? the answers indicate that the angle of 45°, which maximizes the range of projectile motion, does not maximize the horizontal distance when the launch and landing are at different heights.

Part a

Horizontal Distance: 22.5 m

Velocity at which shot putter shot

Angle at which it was shot =

Time of flight is given by the formula:

Taking accleration due to gravity,

Then, Horizontal distance is given as:

Part b

Horizontal distance= 23.86 m

Velocity at which shot putter shot

Angle at which it was shot =

Time of flight is given by the formula:

Taking accleration due to gravity,

Then, Horizontal distance is given as:

Therefore, although the range is maximum for part a but horizontal distance covered is smaller than in part b.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
